Apple recently boosted the speed and storage on its Mac minis, but they missed out on any Blu-ray love. AMEX Digital's Upgrade Kit is designed to fix that. One small problem, though: OS X still lacks native Blu-ray movie playback.

That means using another OS (like Windows 7, via Bootcamp) for Blu-ray playback. Back in OS X, reading and writing Blu-ray discs is possible if you're using software like Adobe's Premiere Pro CS3 with Encore, or the Blu-ray plug-in for Roxio's Toast.

Another thought: the kit costs $200 bucks. Add that to the entry-level Mac Mini's $600 price tag, and you may as well start thinking about other media PC options. Fail. [AMEX Digital via Engadget]
